Abstract:

The methods of performing captive model experiments and using analytical techniques for predicting the stability and control characteristics of submarines at the David Taylor Model Basin are discussed. An outline of Reynolds number scaling issues is provided, and a typical test program is provided for both the straightline basin and rotating arm. The characteristic equations for both the vertical and horizontal planes of motion are provided, as well as the equations for the margin of stability, stability roots, and damping ratio. There is a discussion of the equations of motion and the hydrodynamic significance of the terms in the equations. An uncertainty analysis is provided for the measurements that are associated with performing captive model experiments. MM
